BS EN 1996-1-2:2005:2011 Edition

(1)P This Part 1-2 of EN 1996 deals with the design of masonry structures for the accidental situation of fire exposure, and is intended to be used in conjunction with EN 1996-1-1, EN 1996-2, 1996-3 and EN 1991-1-2. This part 1-2 only identifies differences from, or supplements to, normal temperature design.

(2)P This Part 1-2 deals only with passive methods of fire protection. Active methods are not covered.

(3)P This Part 1-2 applies to masonry structures which, for reasons of general fire safety, are required to fulfil certain functions when exposed to fire, in terms of:

• avoiding premature collapse of the structure (load bearing function)
• limiting fire spread (flames, hot gases, excessive heat) beyond designated areas (separating function)

(4)P This Part 1-2 gives principles and application rules for designing structures for specified requirements in respect of the aforementioned functions and levels of performance.

(5)P This Part 1-2 applies to structures, or parts of structures, that are within the scope of EN 1996-1-1, EN 1996-2 and EN 1996-3 and are designed accordingly.

(6)P This Part 1-2 does not cover masonry built with Natural Stone units to EN771-6

(7)P This Part 1-2 deals with the following:

• non-loadbearing internal walls.
• non-loadbearing external walls.
• loadbearing internal walls with separating or non-separating functions.
• loadbearing external walls with separating or non-separating functions.
